The authors of the text created a free database called AuraDB Free using Neo4j, a graph database, to store a Kickstarter dataset. The dataset contains information about 375k Kickstarter projects from 2009 to 2017, including category, country, and pledge data. The authors imported the dataset into the database using Google Spreadsheets and then created nodes for categories, subcategories, countries, and projects. They also added labels to the project nodes to indicate their state (e.g., successful, failed, canceled). The authors demonstrated various queries to answer questions about the data, such as which categories exist, how many there are, and what is the most successful category or country. They also showed how to visualize the data using Neo4j's built-in visualization tools. The dataset can be used for further analysis, adding more data from other sources, or building a Kickstarter-like app or analytics dashboard.
